Abstract (en)
[origin: WO03072454A1] There is described an optionally flexible and/or polymeric packaging film (e.g. BOPP) having at least one tear line (5) and at least one tab (7) thereon, where the tab (7) has a free end, an end attached to the film and free sides connecting the two ends, the tab (7) positioned so the axis of at least one tear line (5) passes through both ends of the tab (7) characterised in that: (a) at least one of the free sides of the tab (7) taper outwardly from the attached end and the tear line (5); and (b) at least one angle theta (theta) is an acute angle greater than about 5° where theta (theta) is defined as an angle subtending the free end of the tab (7) measured between: (i) an axis defined by the average direction of one of the tab (7) sides averaged over a the last quarter of the maximum length of the tab (7) starting from the attached end; and (ii) an axis defined by the average direction of the tear line (5) along the film. A method of preparing such films and packaging articles (such as cigarette cartons) over-wrapped with such films are also described.
